Application filed November 25, 1908 Serial No. 464,502. H 1

To all whom it may concern:

Be it known that I, W LLIAM HARDIoK, a citizen of the United States, residing at Cadillac, in the county of Wexford and State of Michigan, have invented new and useful Imrovements in Turnbuckles, of which the folowing is a specification.

My invention relates to im rovements in turn buckles designed especia ly for use in situations where the uniting parts are exposed to injury by the elements or accidental reaking and injury from blows; and I have found it particularly adapted to use in connection with bridles holdin in their proper relative position the aralle rails of any car track; but it may a so be employed for a great variety of analogous uses. 5

The object of the invention I accomplish by the construction shown in the accompanying drawings, in which Figure 1 is a vertical, longitudinal crosssection of the sleeve and adjacent parts which constitute the device. Fig. 2 is a side view of the same sleeve having a portion broken away to show the vertical cross-section. Fig. 3 is an end view of the same Fig. 4 is a side view of the right and Fig. 5

sleeve. lefthand nut embodied in the device. is an end view of the same nut.

In the drawinga and b are the two rods, or other structures, which are to be connected longitudinally by adjustable connection. The adjacent ends of these rods are threaded by respectively right and left hand threads as indicated by the portions h and i. e is an elongated right and left hand nut for engaging respectively these threaded ends h and i. This nut may be in any suitable or customary form and should be so constructed that it may be grasped and turned with a wrench. I accomplish this result by making the end portions hexagonal in form, as especially shown by Fig. 5.

d d are lock nuts in the usual form, which are threaded upon the respective portions h and i and which may be turned to or from the nut e so as to lock it in any desired position.

C is a sleeve covering and protecting the operating parts of the device. At one end this sleeve is provided with an interior thread as indicated by 76, and this engages with a corresponding exterior thread in any suitable 'osition u on one of the connected parts, as indicated y In order to make the sleeve of size suflicient to cover the working arts,

it may be necessary to provide the rod with an enlarged portion, u-pioniwhiclrthe exterior thread is cut, as particularly illustrated in Flg. -1. I11 other forms otthe device this enlargement might not-"be necessary; At or:

near the other end of't'hesleeve andin connection with the adjacent end of the other rod or part to be connected, I provide means forengaging these parts againstrevolution. As'such means I have showna series of holes ff in the sleeve, and a corresponding hole 9 in the rod (1. Througlrth'cse holes pins or screws may be removably inserted for looking the two parts together. In the form shown in Fig. 1 there should be an enlargement of the rod a at m, as indicated, so that it will make a close working fit with the interior of the sleeve 0.

The operation of my-device is apparent from the description already given. If it is desired to use the same in connection with a bridle between the rails of a track, the parts of this bridle are indicated by a. and Z). The ends are broughtnear together and the nut e attached and screwed up until the proper ad'ustment is attained. Then the lock nuts (1 d are turned into position, thus retaining the ad'ustment. During this operation the sleeve has been at one side, surrounding one or the other of the rods, and it is now brought up so as to cover and inclose the parts already described, and, by means of the threaded engagement 7c, is fastened to the rod 1). This threaded engagement can be so adjusted longitudinally that the holesf and g at the other end of the sleeve will be in alinement, and the pin, or other suitable fastening means can be inserted. In this way the operating parts of the device are securely protected against accidental injury or against damage by the elements, and when the de vice is used in connection with a bridle between the car rails, are especially protected against ice and snow and against injuries caused by objects passing over or along the track. At the same time a further orsecond ary lock is provided reinforcing the operation of the lock nuts. The sleeve also forms another means of connection between the rods and stifl'cns and reinforces the connection formed by the ordinary turn buckle.

Having thus described my invention, what I claim to have invented, and desire to secure by Letters Patent, is

1. In a turn buckle the combination with the two members to be connected, each having a threaded end portion and a nut con member. t

2.. In a turn buckle the combination with the two members to be connected, each havinga threaded end portion and anutconnecting said members, of a sleeve surrounding the nut, means connecting the sleeve with one of the members for adjustment axially thereof, and locking means for the sleeve connecting the same to the other member, said locking means when engaged, holding the sleeve against adjustable movement.

'3. In a turn buckle the combination with surrounding the nut and having threaded engagement at one\end thereol with one of the members, said sleeve having an aperture at its other end and the other member having an aperture which registers with the aperture in the sleeve.

In testimony whereof I have hereunto set my hand in presence of two subscribing wilnesses.

'ILLIAM llAhDlCK.
